Description

Technical field

The invention relates to a wristwatch comprising a watch case and one of a first and a second band element existing watch strap, at one end of the first band element, a first closure device part and at one end of the second band element a second closure device part for producing a Detachable connection between the two band elements is formed. Furthermore concerns the invention of a watch band of the type just described.

State of the art

According to the latest findings, the wrists of certain population groups show or individuals of such groups have ever larger diameters worldwide. Thereby the differences between the thin and the thick wrists too increasing within a population group. There is one for wristwatch wearers possible consequence of this wrist enlargement that the existing bracelet of her watch becomes too small or that new bracelets do not have the required bracelets Size are available.

Depending on the type of bracelet, there are different solutions to this problem. For bracelets, which consist of many joined, similar members is the Easy solution. You only add one or more additional links to the bracelet added. For this type of bracelet there is also a locking device from CH 625 685 Known which several ways to attach the last (or first) link of the bracelet on the closure device and so a more or less wide Bracelet results.

In contrast, bracelets are made of leather or plastic, for example are and which consist of two parts, which are releasably connected with a closure can be the only solution to the problem of making special oversizes every single bracelet type. However, this has an enormous logistical overhead result. For those affected, they can also purchase a new, larger bracelet considerable costs arise, which are not all ready to bear. Also missing from many customers the willingness to have an intact or maybe even as new watch strap throwing away and buying a new, bigger one.

Presentation of the invention

The object of the invention is to provide a way to extend one of two releasably connected Band elements formed watch band to create their usability is independent of the specific design of the bracelet clasp.

The solution to the problem is defined by the features of claim 1. According to the Invention are only concerned with wristwatches, which have a watch case and a watch band consisting of two band elements. It doesn't matter It matters whether or not a clockwork is used in the watch case. The band elements point at one end each have a closure device part, which together a closure device form with which the two band elements are releasably connected can, so that there are different bracelet lengths.

However, the widest setting also results in a bracelet length that is too small for a specific one Person, according to the invention, is one between the watch case and a band element used tape extension provided. The band extension is on one Detachable side with the watch case and detachable on the other side with a band element connected, the band extension with that of the closure device part opposite end of the band element is connected.

Of course, in an analogous manner between the other band element and a second strap extension can be used in the watch case. It is also natural also possible, despite the sufficient length of the existing bracelet, one or two according to the invention Use tape extensions.

With the tape extension described, an extension can be carried out in a simple manner be achieved by two-piece watch straps. The tape extension can be used both for mounting bracelets with the same and different widths like the width of the original bracelets. Furthermore, both the extent the extension, as well as the visual appearance of the band extension the individual needs of the wearer of the wristwatch can be tailored. The shape considering individual, aesthetic aspects are practically none Set limits.

Two-part watch straps usually consist of a flexible material such as leather or Plastic and have a length-adjustable closure device so that they can adjust to the shape or size of the wrist. The first closure device part consists of a U-shaped bracket, the opening of which is e.g. with a spring pin is closed. To connect the band element to this bracket, there will be an end looped around the spring pin by an angle of 180 ° and then sewn to the remaining part of the band element on the other side, glued or otherwise connected so that the spring pin is within the of the tape element formed loop is located. In the middle of the spring pin is perpendicular to and another pin (hereinafter called a stirrup pin) can be rotated around the spring pin, by wrapping it around the spring pin once. The band element points to this Open an opening for this purpose. The bow pin is slightly longer than the locking bracket and can therefore only be turned around the spring pin until it is in contact with the hinge element on one side and with the locking bracket on the other side. The matching closure device part is on the other band element only from a few holes in this band element at different distances from the End of the band element. The holes lie in a row on the longitudinal axis of the band element.

The detachable connection of the two band elements is now made by punching End of a band element from the side opposite the bow pin a piece is pushed far through the locking bracket and the bracket pin by one the holes of the band element is inserted. When pulling back the band element the hanger pin strikes the locking bracket and thus prevents the band element from slipping out. This connection is released by pushing the perforated band element through the bracket is pushed back until the bracket pin slides out of the hole and the band element then completely (without threading the bow pin into a hole) the locking bracket is pulled out. Depending on the hole through which the hanger pin is plugged in or can be plugged in, results in a slightly narrower or a little more Watch band.

To extend the bracelet, one is attached to at least one of the two band elements attached tape extension according to the invention, the mass of the tape extension are matched to the width of the bracelet. The width of the other end of the belt extension, which can be attached to a watch case can be chosen arbitrarily become. Because a strap extension instead of a watch strap on a watch case is mounted, the width of the belt extension is usually also on the common bracelet widths matched. So the band extension can be as versatile as possible be used.

A strap extension according to the invention preferably has a first fastening device to create a detachable connection between the tape extension and the watch case and a second fastening device for producing a detachable Connection between the strap extension and the watch strap. The advantage of connections that are easily and quickly released from the wearer of a wristwatch and can be restored, is that a tape extension for different Watches or different strap extensions used for the same watch can be without having to switch to a watch store for expensive services must be used.

In a preferred embodiment of the band extension, the second fastening device has several attachment levels. By attaching the bracelet in Different extensions can be implemented for the different attachment levels become.

In a further embodiment of the invention, the band extension consists of two Elements. These are connected to each other, for example, with a type of cardan shaft, so that they can be rotated around a common hinge axis. One of those elements is attached to the watch case and therefore has a first fastening device on. The watch strap is attached to the other element, which consequently has a second fastening device with one or more fastening stages. Belt extensions made of two elements with several adjustment options are suitable especially for a large extension of a watch strap, because the strap extension thanks to the mobility of the two elements better to the shape of a wrist fits as a one-piece tape extension. It is also the case with two-part belt extensions possible to produce several matching elements for one element, which, for example, for mounting on different sized watch cases or for Fastening bracelets of different widths are suitable.

In wristwatches, the two band elements are usually each with a spring pin attached to the watch case. So that the same watch case can continue to be used, the band extension is preferably also with a spring pin on the watch case attached. For this purpose, on two opposite sides of the Watch case usually provided two nose-shaped extensions (French: corne), each one Have a spring pin hole. The extensions are designed so that the two spring pin holes coaxially come to a certain distance, the mounting distance. On Spring pin of the correct size can now be between the two spring pin holes be pinched. The first fastening device corresponds to the device for Attaching a watch strap to a watch case. It essentially exists from a hole into which the spring pin can be inserted. This hole is in the Following called spring pin hole. The length of the Spring pin hole smaller than the mounting width of the two spring pin holes on Watch case. The length of the spring pin is chosen so that it is in uncompressed state is larger than the mounting width, but smaller by a length than the mounting width compressed and thus between the two spring pin holes can be clamped on the watch case. Such in that Spring pin receiving hole of the band extension inserted spring pin looks up out on both sides and can be between the spring pin holes Watch case can be clamped. Instead of a single spring pin hole Of course, several coaxial spring pin holes can also be provided be through which the spring pin can be inserted. But here, too, that applies the total length of all spring pin mounting holes must be smaller than the mounting width. So that the spring pin in the inserted state is rotatable about its longitudinal axis or Belt extension can be rotated around the spring pin, the diameter of the Spring pin receiving hole larger than the diameter of the spring pin.

The second is that the same watch straps can still be used Fastening device is preferably designed so that a watch band also can be attached to the strap extension with a spring pin. Similar to the Fastening a clasp on the bracelet will be one end of the Folded band element, so quasi folded, so that the end of the band element comes to lie parallel to a middle part of the bracelet. By the end of the band element with this middle part e.g. is connected by sewing or gluing at this end of the band element a kind of loop through which a spring pin (analog to the spring pin receiving hole of the tape extension). Here the loop is big enough for the spring pin to be around it when inserted Longitudinal axis is rotatable or the band element can be rotated about the spring pin. The spring pin used here must be longer than the width of the bracelet.

The second fastening device preferably consists of two opposite, plane-parallel surfaces, each with a spring pin hole. The distance between the two surfaces, the bandwidth is larger than the width of the bracelet. So that the spring pin between the two spring pin holes can be clamped between free space for them and they are also coaxial. The length of the spring pin is chosen so that it is larger than the bandwidth in the uncompressed state, but over a length smaller than the bandwidth compressed and thus between the two spring pin holes can be clamped to the belt extension.

In a particularly preferred embodiment of the invention, the band extension is formed such that an inserted into the spring pin receiving hole of the band extension Spring pin parallel to one between the two spring pin holes of the band extension clamped spring pin.

As already described, the band extension consists of two around a common joint axis Rotatably connected elements, this hinge axis is also preferred parallel to the two spring pins.

From the following detailed description and the entirety of the claims there are further advantageous embodiments and combinations of features of the invention.

Ways of Carrying Out the Invention

FIG. 1 shows a perspective view of a belt extension (1) according to the invention, the underside of the band extension (1) is visible. The band extension (1) is like this formed that a watch band by means of a spring pin at the front end (2), and the rear end (3) itself fastened to a watch case by means of a spring pin can be. The front end (2) resembles a hollow cuboid without a lid. In both Side walls (4.1, 4.2) of this cuboid are three spring pin holes, whereby there is a spring pin hole in one side and the other side wall (4.1, 4.2) exactly opposite and together form three pairs of spring pin holes (5.1, 5.2, 5.3), see above that a hole axis (6.1, 6.2, 6.3) through the centers of the two spring pin holes one Pair of spring pin holes (5.1, 5.2, 5.3) exactly perpendicular to the side walls (4.1, 4.2) lies. The bandwidth (7) is equal to the distance between the two holes of such a pair of spring pin holes (5.1, 5.2).

The strap elements of a watch strap that can be used to attach to the strap extension point at those ends with which they are attached to a tape extension a spring pin hole. This is formed by the corresponding one End of the band element transversely to the longitudinal direction of the band by 180 °, so the tape is folded and the end put around at the bottom of the same Band element is sewn, glued or otherwise attached. For fixing of a band element on the band extension is a spring pin through the Insert the spring pin hole so that it looks out a little on both sides and then the two ends of the spring pin between the holes a pair of spring pin holes (5.1, 5.2, 5.3) of the strap extension clamped.

The rear end (3) also resembles a cuboid with the same height. The width is in this example is equal to the width of the front end (2). The cuboid has a spring pin hole (8), the hole axis (9) parallel to the hole axes (6.1, 6.2, 6.3) lies. Through the spring pin receiving hole (8), a spring pin, with which the band extension (1) is attached to the watch case. The case width (10) corresponds to the width of this cuboid or the width of the rear end (3).

Figure 2 shows a wristwatch consisting of a watch case (11) (with clockwork) and a watch band consisting of two band elements (12.1, 12.2), whereby between the watch case (11) and the first band element (12.1) and between the watch case (11) and the second band element (12.2) each have a band extension (1.1, 1.2) is mounted. Figure 2a) shows the wristwatch from above and Figure 2b) shows a cross section through the wrist watch from the side.

The watch case (11) has a pair of each on two opposite sides nose-shaped extensions (13.1, 13.2), the mutually facing inner surfaces of the nose of a pair are plane-parallel and have a certain distance from each other. The mounting distance (15) corresponds to this distance. In each of these inner surfaces of the nose there is a spring pin hole. A hole axis (16.1, 16.2) through the centers of the two Spring pin holes of a pair of nose-shaped extensions (13.1, 13.2) are exactly perpendicular to the two inner surfaces of the nose.

To a strap extension on a watch case with a certain mounting width To be able to install, the housing width of the strap extension must be smaller in any case than the mounting width of the watch case.

Each of the belt extensions (1.1, 1.2) is made in one piece and has only one pair of spring pin holes (18) for fastening the band elements (12.1, 12.2). The tape extension (1.1, 1.2) has the same width at both ends, resulting in a bandwidth (7), which is twice the thickness of the side walls smaller than the housing width (10). A even smaller bandwidth can be achieved by the width of the belt extension on corresponding end is chosen smaller than the width at the end with the spring pin receiving hole (19).

By means of a spring pin through the spring pin receiving hole (19) of the band extension (1.1, 1.2) is inserted, the strap extension (1.1, 1.2) on the watch case (11) be fixed by the spring pin between the two spring pin holes in the Nose inner surfaces of a pair of nose-shaped extensions (13.1, 13.2) clamped becomes.

In Figure 3, a one-piece tape extension (1.3) is shown, which over two pairs of Spring pin holes (20.1, 20.2) for fastening a band element. In Figure 3 a) from above and in Figure 3b) from the side. The spring pin receiving hole (21.1) is also in Figure 3a) shown, although it is not visible in this view. The first pair of Spring pin holes (20.1) in a first hole spacing (22.1) and the second in one Larger, second hole distance (22.2) from the spring pin hole (21.1). The bandwidth (7) is again smaller than the housing width (10). By means of a through the spring pin receiving hole (21.1) spring pin inserted at one end of the band extension (1.3) the strap extension (1.3) is attached to a watch case.

By using one or two such belt extensions (1.3) and by fastening the band elements in one of the two pairs of spring pin holes (20.1, 20.2) of the strap extension (s) used (1.3), a watch strap can be used in many different ways be extended. By using two belt extensions (1.3) one maximum watch strap extension twice the size of the second hole spacing (22.2) can be achieved. The minimum watch strap extension is when in use a single strap extension (1.3) and use of the spring pin-hole pair (20.2), equal to the first hole spacing (22.1).

Figure 4 also shows a one-piece tape extension (1.4) with two pairs of spring pin holes (23.1, 23.2) for fastening a band element. In Figure 4a) from above and in Figure 4b) from the side. The spring pin receiving hole (21.2) is also shown in Figure 4a), although it is not visible in this view. In contrast to that shown in Figure 3 Belt extension (1.3), the bandwidth (7) is a little larger than that Housing width (10). It corresponds exactly to the mounting width (15) of the corresponding one Watch case. This means that the original watch bracelets can also be attached to the strap extension (1.4) or bracelets with the same bandwidth.

A belt extension according to the invention can of course also be designed such that whose bandwidth is larger than the installation width.

A two-part belt extension (1.5) is shown in Figure 5. The back end with the Spring pin receiving hole (21.3) forms the first element (24.1) and the front end three pairs of spring pin holes (25.1, 25.2, 25.3) forms the second element (24.2) of Belt extension (1.5). The first element (24.1) has a T-shaped shape (lying), the spring pin receiving hole (21.3) through the crossbar of the T and parallel an articulated hole (26) to the spring pin receiving hole (21.3) through the longitudinal bar of the T runs. The second element (24.2) has the shape of a U with a broad base (also lying). The spring pin-hole pairs (25.1, 25.2, 25.3) run through the base of the U and in each leg of the U runs parallel to the hole axes of the spring pin-hole pairs (25.1, 25.2, 25.3) a hinge hole (27.1, 27.2). The distance and length of the two Legs of the U-element correspond to the width respectively. the length of the longitudinal beam of the T element. The two elements (24.1, 24.2) of the band extension (1.5) are like this arranged that the hinge hole (26) in the longitudinal beam of the T-element and the two Articulated holes (27.1, 27.2) in the legs of the U-element are coaxial and consequently a propeller shaft (28) can be pushed through, causing the two elements (24.1, 24.2) around a common hinge axis, namely the longitudinal axis of the drive shaft (28) are rotatably connected.

The width of the base of the U-element is chosen larger than the width of the crossbar of the T element. The bandwidth (7) therefore corresponds to the mounting width (15) and is a slightly smaller than the housing width (10) of the band extension (1.5). So it is possible the strap extension (1.5) between the strap elements and the watch case to assemble an existing watch. You can continue to use the original bracelets or extend.

In summary, it should be noted that it is the belt extension according to the invention allows the bracelet of a wristwatch to be closed in several stages in a simple manner extend. Both the same watch band can be used or another bracelet is mounted, the width of which is less than, equal to or greater than that of the original volume.
